These analyses revealed that FSP1 levels were upregulated in multiple cancers compared to their corresponding normal tissues, including LUAD, LUSC, kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), kidney chromophobe (KICH), stomach adenocarcinoma (STAD), liver hepatocellular carcinoma (LIHC), and uterine corpus endometrial carcinoma (UCEC) (Fig. 4a). Here, AIFM2 is linked to gastric adenocarcinoma.
